SPECIFICATION forming part of Letters Patent N o. 536,059, dated March19, 1895 Application filed December 3, 1894. Serial No. 530,702. (Nomodel.)

To all whom, it may cowcrn.- l

Be it known that LGUSTAF ARvID ANDER- SON, asubject of the King ofSweden and Norway, residing at Waynesborough, inthe vcounty'of Franklinand State of Pennsylvania, have invented certain new and usefulImprovements in Compensating Gears; and I do hereby declare thefollowing to be a full, clear,

and exact descriptionof the invention, such as will enable othersskilled in the vart tofwhich fit appertains to make and use the same.

This invention relates to compensating gears; and it consists inthenovel construction and combination of the parts hereinaf- V I5 ter fullydescribed and claimed, wherebythe device'is reduced to a very simpleform and is very" inexpensive to construct.

In the drawings: Figure 1 is an end view 'of the compensating gear. Fig.2 is a-longitudin'alsection taken on the line man in Fig. 1.

A is the shaft which supports the compensating gear. This shaft isjournaled in bearings A' of any approvedconstruction.

B is the driving wheel or its equivalent, journaled upon the shaft A.

C and C are the power transmitting wheels or their equivalents, such aschain wheels, rope sheaves or belt pulleys.

The wheel C is Vjournaled upon the' shaft A, and the wheel C is securedto the said shaft.

D and D' are two coupling wheels. The wheel D is Ajournaled on the shaftA on one side of the driving wheel B, and vis formed integral with or isotherwise firmly secured to the wheel C. The wheel D is secured to theshaft A on the other side of the driving y wheel B from the wheel D.

fis

E E are two guide wheels arranged atan angie/to each other, journaled onthepins e, and carried by the driving wheel B, the axes of .the pins ebeing arranged crosswise of the axis of the shaft A.'

The power transmitting wheels are preferably of equal size, landl alsothe coupling but this Vis not essential if the wheels v are otherwisecorrectly proportioned to eect .pso

l the same results. F is an endless flexible connection, such as a. cordor chain. The middle loops ofv this 'resistances iiexible drivingconnection pass overl the respective guide wheels E, and the end loopsand are formed to engage the chain so that they cannot slip.

A platefis secured to the end of the shaft A to prevent the wheels C andD from-slip ping oi it.

When the power transmitting wheels C and C are of the same size, thewheels D and D are also equal .to one another in size, and when thedriving wheelB is revolved iri either direction it revolves thewheels Cand C with equal velocity, through the wheels D and D and the iie'xibleconnection, as long. asthe wheels C and C are Working against equalWhen, however,.the resistance to one power transmitting wheel becomesgreater than the resistance to the other power transmitting wheel, thecoupling wheels D and D are revolved in opposite directions, and thevelocity of the power transmitting Wheels becomes unequal and inverselyproportional to their respective resistances.

The guide wheel pins e may engage with the driving wheel B, but. inorder to take up all the slack of the Iiexibleconnection, and notrequire that it should be of a certain exact length, the pi n's e arepreferablycarried by a bracket G. Two rods hh are pivoted to the bracketGr by the pin H, and are preferably arrangedl substantially in vlinewith the guide sheaves lto which they pertain. The rods h h pass looselythrough holes t' in the brackets i formed integral'with the wheel B, andhavev 'nutsj and washersj on their ends.

IOO

transmitted .by them to the road wheels are y inversely-'proportional tothe resistances to be overcome;

In a compensating gear, the combination1 with thedriving wheel Bprovided with brackets i', and the coupling wheels arranged concentricwith 4the wheel B and one on each side of it; of the bracket G, the rodsh h pivoted to the bracket G and passing through holes in the bracketsi?, the adjustable supportingsprings connected to the said rods,

.th'e'guide sheaves journaled in the brackets G, and a flexible endlessdriving connection passingaround the said guide wheels and couplingwheels, substantially as and for the VIn testimony whereof I aiix mysignature in presence of. two witnesses.
